On-line measurement of pulverized coal fineness on a 300 MWe power

Particle size distribution (PSD) of coal powder, so-called pulverized coal fineness (PCF) [2], is a crucial parameter in coal-fired power plants, with a significant effect on combustion efficiency [3], wear of equipment, and emissions [4,5]. Not only reliable and repeatable, but real-time measurement of PCF is required before any optimizations [6].

Numerical and experimental analysis of pulverized coal mill …

In pulverized coal-fired (PCF) power plants (PPs), coal is pulverized in a mill, and it is then transferred to the burners and furnace volume for combustion. Depending on the physical and chemical properties of the coal, different types of pulverizing systems (e.g., vertical and horizontal air-swept (Fig. 1 a and b)) can be used. Horizontal air ...
